COVID-19 'Break-Through' Cases In Lane County To Be Expected

Oregon made national news recently after four people tested positive for COVID-19 at least two weeks after they were fully vaccinated. Two of the so-called “break-through” cases are in Lane County.

Health officials say because none of the approved vaccines are 100% effective, some cases like these are to be expected.

At a press briefing Tuesday, Public Health spokesperson Jason Davis noted the Pfizer vaccine has an efficacy rate of about 95%   

“That means that five out of one hundred people who received the vaccine would potentially test positive for COVID-19 if they came into contact with someone who was sick.”

Davis said some people develop a false sense of security after getting immunized. The vaccine is not thought to prevent viral transmission-- so masking, distancing and hand washing should be continued whether you are vaccinated or not.
